To all whom tt may concern: v

Be it known that I, HORAGE E. SMYTHE, residing at Oakmont, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Im'provements in Gas-Producers,' of which improvement the' following is a specific'ation.

It is incident to the operation ofgas pro ducers that the charge becomes so acked and wedged'therein that when the as es are removed from the lower part, the charge will notfall down but will remain Suspended and it must be broken up more or less by pokers inserted through holes in the top, not only to break 'up the charge but also to remove any portions adhering to the walls of the roducer. This difliculty is especially inci ent to the operation of gas producers having Water seals ;and is objectionable for the reason that the holes made by the pokers will permit the air and steam forced in' with the blast, to pass up 'and ignite the gas in the upper art of the chamber.

T e present invention has for its object the breaking up of the charge in the furnace' or a portion thereof from below atthe time the ashes are removed, sothat the weight of the up er portion of the charge will destroy any ad hesion to the sides of the furnace and permit the charge to drop down without any material breaking up.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification, Figure 1 is a sectional elevation of a Water sealed gas producer having my improvement appled there- Fig. 2 is a similar view on a plane at right angles to that shown in Fig. 1. Fig. 3 is a sectional lan view on a plane indicated by the line I III Fig. 1. Fig. 4 is a sectional view 'similar to Fig. 2 illustrating a modification of my improvement. Fig. 5 is -a similar View on a plane at right angles to 'Fig.-.;4 and Fig. 6 is' a sectional lan view on a lane indicated -by the line H -III Fig. 4. n the practice of my invention, the body of the producer 1 is supported upon suitable side piers 2 and the mantleplates 3 which in turn' are supported by the piers or abutm'ents. The interior of the producer is in communication through the openings 4 below the mantle plates With the basins 5 at the sides of the furnace. These nantle plates are below thelevel of the water contained in these basins, so that' the water forms a perfeet seal and the ashs, etc., can be removed from the producer through the openings 4 into the basins, whence they are to be Withdrawn by a rake or other suitable means. As is customary in the operation of water sealed producers, the charge within the producer is supported by the ashes, etc., resting on the 'bottom plate 6, no grate being employed.

As these ashes are removed the charge Will gradually settle, provided it does not arch over or does not adhere too tightly to the sides of the roducer.

As herein efore stated a oker is used in case of the failure of the discharge to descend from'either of the causes stated to break up the arch or loosen the adhering portions from the sides of the furnace. To avoid the use of pokers and the consequent formation of holes through the 'upper `portion of the charge I provide fora stirring up of the portion of thecharge near the lower end of the producer, by means of a series of arms 8, extending radially from a hollow shaft 9, mounted in suitable bearings 10, in the walls of the producer and connected at one end to the blast box 11. These arms as clearly shown in Figs 1 and 3 are made hollow and' provided with perforations for the escape of the blast therefrom. The perforations are protected by hoods 12 which Will' prevent the entrance of ashes into the openings and clog the same. This shaft may be rotated by any suitable means as for example that shown consisting of a chain' 13 passing around a sprocket wheel in the shaft and around a drum 14 s'uitably arranged at the 'top of the' producer and suitably driven by a crank or handle. After-the ashes etc., have been removed from the ash pan or pit, and the char e fails to descend this sha'ft is rotated an the arms Will break up the closely compacted material in the lower portion of the charge so that it Will drop, leaving the per portion unsupported. The weight of ths unsupported mass will cause t to descend tear-ing away any adhering particles from the walls of the producer. This downward movement in mass will not materially disintegrate the charge. This shaft With the radial arms does not in any respect operate as or serve the purpose of a supporting grate, the arms being separated such a distance that they Will not present any material obstruct on to the usual settling down of the charge into the ash pit.

enployed simply for loosening the charge' and..

the blast can e introduced through 'nozzles and' connected to" the supply pipe by vertical pipes 16. As *th-esma with ts arms I is located n a portion of the furnace where it subject to considerable heat, `pro-.

p i shaft, said'boxhavingan ou'tlet pipe 19. In addition to the bla'stintroduced by the no`z-. zles it may also be introduced at the same time through blast boxes 20 which are substituted and erorm the function of the 'mantle lates eretofore described.

It wil be observed that the arms 8 are so located in the lower portion of the produc'er that when rotated they Will tend to force the ashes down and towards one or the other of the openngs in the ash'pit from which the ashes are removed. 4

I claim herein as my invention:

1. 'A- gas producer having in combination means for su porting the charge and means arranged in t e producer above and adjacent' to the lower porton'of and adjacent to the charge supports 4 and movable in vertical planes for loosening the lowerportion of the charge.

2.- A gas' prduc'rfihaving discharge openings at its lower' ende., a hasin extending above the upper wal-lsj..-of said o enings said basn frm'ing the siipport for the charge, a shaft horizontally: e xtending across the producer in a plane above and adjacent to the discharge openings and provided with radial arms, and means for rotating the shaft.

3. 'A water sealed gas producer having in combinaton therewith, ashaft horizontally extending across the producer in a plane -above the (water 'seal and provided with arms, means for rotating the shaft, and

means for introducing a blast of air into the producer.

4. A water sealed gas producer having in combination therewith a hollow shaft eX- tending horizontally across the producer in a plane above the water seal and provided With hollow arms having perforations,'means for rotating the shaft and means for introducing a blast into said shaft.

In testimony Whereof, I have hereunto set my hand.
